摘要
研究了Ti、B微量元素对焊缝金属韧性的影响。结果表明 ,加入Ti、B微量元素有利于改善焊缝金属韧性 ;同时适当的Ti、B配比才能获得高韧性的焊缝。
The effect of trace elements such as Ti, B on toughness of welded metal was studied. The results show that addition of trace element is favourable improving welded metal toughness. It is noted that the Ti and B should have appropriate proportion.
